Chemical Structure

16Alpha-Hydroxytestosterone CAS 63-01-4 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

16Alpha-Hydroxytestosterone (CAS 63-01-4), molecular formula C19H28O3 and molecular weight 304.42 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 16Alpha-Hydroxytestosterone (C19H28O3) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 16Alpha-Hydroxytestosterone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
